I compile using MingW (gcc 4.7.2) and normally I use
 -Wall -W.

But this gives tons of warnings. Hence I use these to supress most of
them:
  -Wno-unused-but-set-variable -Wno-unused-function 
  -Wno-strict-aliasing

This results in only these warnings:
 missing/inet_ntop.c: In function 'inet_ntop':
 missing/inet_ntop.c:146:44: warning: 'best.len' may be used uninitialized in this function [-Wmaybe-uninitialized]
 missing/inet_ntop.c:117:5: note: 'best.len' was declared here

Must be one of the oldest file in tcpdump. From 2005.
